.TQQZZ .whom it may concern:

Beit knoivn that RONALD F. McFnnLY, a citizen of the United States,residing at Beverly, in the county of Essex and State ofllflassachusetts,.have invented certain lm- -provements ln TackingMechanisms, of

which the following description, in connec' tion with the accompanyingdrawings, is a specication, like reference characters on the drawingsindicating like parts in the several figures.

This invention relates to machines for use in the manufacture of bootsand shoes and particularly to nailing or tasking apparatus `used in suchmachines.

The invention is shown for exemplicationI as embodied in a pullingovermachine of the type shown in the prior ida-tent No. 663,777 granted onmy application December 1l, 190G, but protection is sought for all usesfor which this invention is adapted.

The general object of this invention is to provide for variations in thepositions at which tacksshall be inserted, and it may be also in thenumber of tacks driven.

A very important feature of the invention is found in the provision ofmeans for changing the lateral position in which the toe tack isinserted. lit is found in the use of this pulling-over machine, andsimilar conditions might be met in other machines, that right and leftshoes made on crooked lasts can be moet satisfactorily secured at inaccordance with the preferred embodi- 'ment of this invention the tackerand Wiper are adjusted together, and also the toe gripper of the machineis adjusted in company therewith.

ln accordance with another feature of this invention provision is madefor adjustment to vary'the distribution of the tacks to the toe and sidetackers. This feature of the invention solves the problem presented infactories making styles of shoes which require the upper to he securedat different points. `For example, shoes hasni: short vamps re.-

quire to be pulled and fastened by a tack Close to the toe at each sideof the last. When these shoes are made on lasts which latented Apr. 13,1915.

have high or prominent toes and are relatively thin between the toe andthe instep the shoe requires to be pulled and fastened by a tack drivenWell back along the ball of the. last. To meet these varying conditions,each side tacking mechanism of the machine is equip ed, in accordancewith a preferred form o this invention, with the maximum number ofdrivers, tack holders and conductors which Will at any time be requiredand the tack supplying and distributing mechanism is constructed andarranged to deliver the Whole number of tacks or a selected series oftacks. For this purpose novel means, Which may be independent of theseparating mechanism, is provided for stopping the deliveryof tacks fromselected raceway grooves whereby a varying predetermined number andarrangementof tacks is delivered into position to be driven by theselected drivers.v These and other features of this invention,including` certain details of construction and more importantcombinations of parts, will appear in connection` with the followingdescription of the illustratedmachine and then will he pointed out inthe claims. f

Figure 1 is a side elevation of a pullingover machine equipped with thepresent improvements; Fig. 2 is a perspective view of the toe tackdriving mechanism; Fig. 3 is a perspective Viewr of the tackdistributing mechanism; Figs. 4, 5 and 6 are front views of the tackcontrolling mechanism in different positions of adjustment Withaccompanying diagrams to show the arrangement of tacks in the shoefollowing from each adjustment; Fig, 7 is a side elevation of the adjlisting devices.

l The machine comprises the head 2 which is supported on a post and hasbearings for a shaft 4 from which is reciprocated a rack 5 that drives atack lifter in the hopper 6. From the lifter the tacks gather inrafceway grooves, Fig. 3, `which are inclined. dovvnwardly toward thetoothed separating slide l() which, by reciprocatory movement across theends of the raceivays, takes a tack from each groove that is open anddelivers i t to the appropriate tack tube 12 by Whichit is conducted toits tack pocket in the side or vthe purpose of this description may becon sidered as a single member with tack grooves therein, is cut away atits lower end above the separator slide 10 and its cooperating parts toreceive plates 22, 23 that have passageways 24 cut through them inposition for alinement, respectively, with. the first and second and thesiitth and seventh race-l way grooves, The upper portions of the opposedlateral walls forming the sides 0f the passageways 24 are extendedinwardly.' asv fingers 24 located below the tack head supportingsurfaces of the raceway block in position to be projected transverselyacross the tack' grooves in the path of the tack stems's may be seenfrom the illustration in' Figs. 4, 5 and 6. This embodiment of theAinvention therefore, presents a tack controller'22, 24a, 24a for thefirst and second tack grooves which is located on the left side of thefirst groove and on the right hand side of the second groove, and asimilarly arranged controller 23, 24a, 24 for the sixth and seventhgrooves, the lower wall of the passageway being located below .the stemsof the tacks in the grooves where it extends across the grooves and theintervening structure of the block 20. The plates have overlapping endsboth of which are operatively connected with an adjuster 25 which can berotated by a screw threaded block that is adapted .to be turned by thetool 26 through an angle and in directions appropriate to separate theplates farther (Fig. 6) from their normal relatiornFig. 4,01' to drawthem closer together, Fig. 5. The passageways 24 are so proportioned andlocated relatively to the raceway grooves that when the plates are inthe central position, Fig.' 4, all the raceway grooves arekopen andtacks will be sej'varated and fed for insertion as indicated in thediagram that is below Fig, 4. When the plates 22, 23 are 'drawn closertogether by the manipulation fof the adjuster as represented in Fig. 5the plates close the first and seventh raceway grooves and permit thedelivery of vonly five tacks and these tacks are the ones which go intotubes associated with drivers that insert them in the relation shown inthe Fig. 5 diagram. lVhen the adjuster is shifted to the position shownin Fig. G the plates 22. are separated and close the second and sixthraceway grooves thereby cutting out the intermediate tack as inthe Fig.6 diagram. By this means different predetermined numbers andarrangements of tacks can be secured without changing the running partsof the machine.

To prevent liability of unauthorized tamperingA with the adj uster it islocated under the cover plate 21 which has to be removed jbymanipulation of the thumb and finger studs 19 in order to uncover thehole through which the adjusting tool 26 is to be inserted. This tool isto be in the custody of the foreman whose directions as to the numberand arrangements of the tacks is to be followed.

similar arrangement for delivering one or y :mother of a pluralityof-tacks to a toe tacker having two or more drivers might be employedbut to save space and duplication of parts and to obtainother advantagesthe toe tacker is instead madelaterally adjustable to insert a tack ator on either side of the median line of the machine and .preferably inany one of many locations whereby it is adapted for operation on rightand left shoes of more or less crookedness. To this end the toe tackerarm 35 which is hung upon the frame at 36 for inward and outwardswinging is pivoted at 38 for lateral swinging movement. It is alsotransversely slotted at 40 to receive a cross bar 42 connecting the widespread'ends of the forward fork 888 'of the mechanism by which it isactuated inwardly to tacking 'position and outwardly to position forclearance.. This mechanism in other respects than the pres'- ence ofthis bar and the width of this fork' may be the same as shown in Fig. 39of my prior patent. The guideway in the machine ,head 2 throughwhicl.the arm moves is also made wider than the arm and it is overioo laid bya plate 45 in which the arm fits as. 4 to wid h but can move freelyforwardly vand backws rdly. This plate has a laterallyl ex'- tendedVtoothed arm 4G thatis engaged bya segment rack 4S connected with ay handlever 50 in which a spring pin is held to rengage a fixed ratchetplate52 for locking the lever with the plate 45 andthe toe 'tacker arm inlaterally adjusted position. The conductor tube' l2'for the fourth. tackis secured to the tacker arm for adjustment with it, said tube .ieingloosely connected to the'raceway block to permit this movement.' The toegripper may haveits bar G0 guided in the plate 45',

as shown in Fig. 2, for lateral movementl with the toetacker and the toeWiper 62,

which lays the'upper upon the shoeinnersole l laid in the properposition -under;the. tack from the laterally adjusted tacker.

In the use of the machine, the toe grippersseize' and pull the upper asusual,

and side s the pairs of jaws of the `double side.gripz-,fiil

' incense ing edect is not desired, as may be the case in some shoes,the Fig. 'adjustment is made to cut out the first andseventh tacks. It

on the other'hand the intermediate tacks are not required, the Fig. 6adjustment vvill discontinue the delivery of the second and sixth tacks.

because all the pulling-over tacks have to be removed from all Weltshoes and they are taken out from McKay shoes to a large extent for thelasting operation. The toe tacker is adjusted for the shape or'the lastthat is in the machine and with it is also esv ' gang means forinserting a plurality of tacks into each` side of the shoe, and meanswhich adjuste'dvthe toe Wiper andthe toe gripper. This. adjustment canbe made at any time, either before 'the machine is started, orinitially, or supplementally Whilelvlthe gripper holds the upper.
